I for one am impressed the protagonist was able to use only single syllable words, just like his boss accused.

Addendum: “Uh-huh” and “Okay” don’t count. The one is a subdermal interjection (defined as unwortische in the 1847 Lexographical Congress of Neutral Moresnet); the other, a 19th century political slogan for a second-rate president. Neither deserves a place in any serious dictionary.
